The former Villarreal winger moved to Palace on Friday.
Spain international Pino has signed a five-year deal and will take the No10 shirt with the Eagles.
Pino said, “I’m very happy to be here. It is a dream of mine to come to the Premier League, to a historic club like Crystal Palace, and I hope that I can help the team.”
Palace chairman Steve Parish also stated: “It’s fantastic news that Yeremy – an exciting young talent, with already such an impressive record in domestic, European and international football – has chosen us as the next step in his career.
“With an exciting season ahead for the club, competing on multiple fronts, he is a player whose talents Palace fans will particularly appreciate – and I look forward to seeing him step out at Selhurst Park.”
